Abstract

A process for making paper to enhance the dry strength of the paper produced without substantially reducing its softness comprising adding to a bleached pulp furnish, separately or together, (1) an anionic polymer selected from the group consisting of carboxymethyl guar, carboxymethyl bean gum, carboxymethyl hydroxyethyl guar, and a carboxymethyl hydroxypropyl guar, with (2) a cationic polymer selected from the group consisting of a cationic guar, a cationic acrylamide copolymer, a cationic bean gum, a cationic amine-epichlorohydrin wet strength resin, and both a cationic wet strength resin and at least one of the other said cationic polymers, a composition for adding to a paper-making pulp slurry comprising the said polymers, a method for making the said composition, and a paper product containing the said composition, are disclosed.
